WACO, Texas -- A nine-run fourth inning erased a four-run Baylor lead and propelled Missouri to a 14-11 victory over the Bears in Saturday night's Big 12 Conference action at Baylor Ballpark. Missouri (28-11, 9-5) clinched the series with the victory; the Tigers have won the series in three straight trips to Waco. Baylor (21-19, 6-11) has lost six of its last seven against Missouri, including four straight at Baylor Ballpark.

Baylor fell to 28-4 all-time in three-game Big 12 Conference series at Baylor Ballpark since the facility opened in 1999. Missouri has three of those four series wins, posting two-games-to-one victories in 2003 and 2005. The Bears' only other three-game Big 12 series loss at Baylor Ballpark was a two-games-to-one loss to Texas Tech in 2001.

The Bears have been swept in a three-game Big 12 series at home only once - Oklahoma State in 1998. Baylor has been swept in a three-game series at Baylor Ballpark only once - UC Irvine in 2004.

Missouri sent 13 batters to the plate in the fourth and turned a 7-3 deficit into a 12-7 lead. The Tigers collected seven hits, walked twice and made use of one Baylor error. Brock Bond's one-out RBI single gave Missouri an 8-7 lead, and Aaron Senne's three-run home run to left-center capped the frame. The nine-run inning tied for the highest-scoring inning ever allowed by a Baylor staff in a Big 12 game; the Bears allowed a nine-run seventh at Texas Tech in 2004.

The Tigers pushed their lead to 14-7 with a pair of runs in the fifth. Baylor got two runs in the fifth on Matt Czimskey's third home run of the season. The Bears posted another two-spot in the seventh thanks to a Shaver Hansen RBI double and a Paul Miles RBI single. However, Kyle Gibson allowed only a ninth-inning, one-out Czimskey single in 2.0 scoreless innings to stymie Baylor's comeback bid and earn the save, his seventh of the season.

Neither starter factored in the decision. Baylor's Randall Linebaugh faced three batters in the fourth and allowed six runs on six hits and a walk with one strikeout in 3.0-plus innings. Missouri's Rick Zagone also allowed six runs on six hits and a walk with no strikeouts over 2.0 innings.

Greg Folgia (3-3) earned the victory, allowing five runs on 10 hits with two strikeouts in 4.2 innings of relief. Wade Mackey (1-1) was saddled with the loss; he was touched for seven runs, only two of which were earned, on six hits and one walk with one strikeout in 1.0-plus inning of relief.

The highlight of the night on the mound for Baylor was Willie Kempf, who closed the game with 4.2 innings of one-hit shutout relief; he walked one batter and recorded a career-high six strikeouts.

Baylor tallied 17 hits on the night, the most by a Baylor squad in a Big 12 game since a 17-hit effort at Kansas in 2005. It was Baylor's highest hit total in a Big 12 home game since a 23-hit performance against Missouri in 2003. Six Bears had multiple-hit nights, led by Czimskey, Hansen and Dustin Dickerson who all had three-hit, two-RBI outings.

Senne, Jacob Priday and Evan Frye turned in three-hit efforts for the Tigers; Senne finished with four RBI and was a triple shy of the cycle.

Baylor and Missouri conclude their three-game series Sunday at 1 p.m. CDT. The Bears send freshman right-hander Kendal Volz (5-1, 4.93 ERA) to the mound. The Tigers have not announced a starter.
